What is the ASTM equivalent to hardox 400 equivalent

The steel plate and strip after hot rolling treatment are generally called hot rolled plate. Compared with other steel plate processing industries, HARDOX 400 equivalent, hot rolled plate has these characteristics. First, low hardness, easy processing. Compared with other steel needs special mechanical equipment, hot rolled plate is a very convenient for processing. Second, good ductility, not easy to break, good compression capacity, long service life. Third, the manufacturing process is simple, and the price and cost are relatively cheap compared with other steels.

Normalizing is a heat treatment that improves the toughness of steel. After the steel components are heated to 30-50°C above the Ac3 temperature, they are kept for a period of time and then air cooled. The main feature is that the cooling rate is faster than annealing but lower than quenching. During normalizing, the crystal grains of the steel HARDOX 400 equivalent can be refined in a slightly faster cooling. Not only can satisfactory strength be obtained, but also the toughness (AKV value) can be significantly improved and reduced The tendency of the component to crack.

How to distinguish the inferior steel plate? 1. The surface of the fake and inferior steel plate is easy to produce scab. 2. The material of fake and inferior steel plate is not uniform and there are many impurities. The surface of fake and inferior steel plate is often pitted. Pitting is an irregular and uneven defect on the surface of HARDOX 400 equivalent, steel plate caused by serious wear of rolling groove. Due to the pursuit of profit by the manufacturers of fake and inferior steel plates, the groove rolling often exceeds the standard.
